大采高小煤柱回采巷道围岩控制技术研究

Research on Surrounding Rock Control Technologies of Narrow Pillar of Mining Roadways in Large Mining Height Face

本文选取大采高小煤柱回采巷道围岩的稳定性与控制技术为研究对象,通过运用理论分析与数值模拟相结合的研究方法,对巷道上覆岩层的结构及其围岩的稳定性进行综合分析,研究得出锚杆支护与巷道围岩稳定之间的相互作用关系,并在此基础上总结出小煤柱巷道支护关键技术。

This thesis pick the stability and control technique of surrounding rock of narrow pillar of mining roadway in large mining height face as research object,using the research method of combine theoretical analysis and numerical simulation to comprehensive analysis the structure of rock layer and the stability of surrounding rock and find out interact relation bolt supporting and the stability of surrounding rock of roadway,finally summarize the key technique of roadway supporting with narrow pillar.
